BOBBIN.

Specification of Letters Patent.

Patented Feb. 8, 1921.

i To all lwhom it may concern.:

' Be it known that I, IVILLTAM HENEY STORES, a subject of the King of Great Britain, residing at 2 Lydgate road, Coventry,-

in the county of `Warwick, England, have invented new and useful Bobbins, of which the following is a specification.'

The object of this invention is .to provide means by which the washing, or otherwise treating, with liquid, of artificial filaments, fibers, or the like, wound upon bodies, such as bobbins, can be effected in a more expeditions, economical and efficient, manner than hitherto.

Such filaments, fibers, or the like, are, after being formed in the coagulating bath. usually wound on to bobbins made of impervious acid-resisting material (such, for

instance, as glass, or stoneware.) and are afterward washed to free them from chemicals and by-products and then the said filaments, fibers, or the like, then being dried and subsequently removed from the bobbins for further treatment. Owing to the thickness of the layers ofy closely wound material upon the bobbins the washing process has been slow and the result not satisfactory.

The object of the present invention is to overcome these difficulties and effect economy in the number of bobbins and quantity of washing water, or other liquid, required in carrying on the process and at the same time effect the washing in a more expeditious, complete and lsatisfactory way than hitherto.

Accordingto this invention the bobbins, or equivalent devices, which carry the filaments, fibers, or the like, are provided with porous, reticulated, or equivalent, material which will lafford drainage for the filaments, fibers, or the like, wound thereon and allowof the-ready passage through, or between, them of the Vwashing water, or the like. ISuch porous, reticulated, or equlvalent, material may, for example, be metall gauze, or other material which will resist corrosion, such as knitted, or woven, fibrous material (cotton, or wool, for example), readily pervious to liquid. The said ma-. terial may be applied in any suitable way; for example, it may be in tubular form, passed onto the bobbins, or it may be in strip form which can be held on the bobbins by sewing, or the material can be secured by means of any suitable devices, such, for instance, as rings, or bands.

rIfhe accompanying drawing shows in eleyation 1n F lgure 1, in longitudinal sect-ion 1n F 1g. 2 and in Fig. 3 in plan partly in transverse section (on the line Fig. 2)

an example of a bobbin provided with mate' rial suitable for the purposes of this inven- V tion, but it is to be understood the invention is not limited to the use of this precise example.

a represents the bobbin, b represents the porous, reticulated, or equivalent, material such as fabric of cotton, wool or other Inaterial of a character and formation which will not cause injury to the silk, and with which the said bobbin is provided in accordance with this invention and c represents the filaments, fibers, or the like, wound upon the said material b.

It will be evident that the invention is not limited to-the use of any particular material as any material which will answer the purpose, as regards supporting the filaments, fibers, or the like, and allowing of the passage of liquid and will not be objectionably acted upon by the chemicals with which it comes in contact, may be employed and it will also be evident that any suitable bodies other than bobbins may also be used and that, although we have specially referred to washing, the invention can also be applied in connection with operations, other than washing, in which liquids are required to be passed through materials wound, or su ported, upon bobbins, or other bodies.

Vhat I claim is 1. A bobbin having an imperforate exterior, and a liquid-permeable sleeve there on upon which thel fiber to be treated is wound, and through which a treating Huid will readily pass between the wound fiber and the exterior of the bobbin.

2. A bobbin having an imperforate exterior, and a textile spacing sleeve thereon upon which the fiber to be treated is wound, and through which a treating fluid will readily pass between the wound fiber and thel exterior ofthe bobbin.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.l
